Eltako Phase dimmer DL-PD-300W-RLC-HS DALI DT4

Phase dimmer with DALI control input for DIN rail EN 60715 TH35. Dimensions: 98 x 17.5 x 56 mm. Protection class IP20. Suitable for dimming 230 V LED retrofit lamps via DALI. Converts the DALI dimming level into a voltage with phase-cut or phase-control. The minimum dimming level (MIN LEVEL) is adjustable via DALI. Additional operating mode as a switch (DT7 compliant) from firmware version 3.5. The module represents a participant on the bus and is addressable accordingly. Double connection terminals for easy daisy-chaining of the DALI bus. Dimming range 0.1% - 100%. Supply voltage 230 V AC. Output load range 10 - 300 W. High efficiency. Configuration via PC software DALI-Cockpit.

Function: The DALI-PD serves as an interface between classic dimming technology (phase dimming) and DALI, adhering to the standard for DALI Control Gears (IEC 62386-102) and Device Type 4 devices (IEC 62386-205). The DALI-PD interface converts the desired dimming level into a corresponding voltage signal with either phase-cut or phase-control. The universal dimmer operates as either a phase-cut or phase-control dimmer depending on the load. The operating mode can be queried via DALI (DT4). The dimming characteristic is logarithmically scaled according to the DALI standard. The phase control provides a cut or uncut sine voltage. The physical MINLEVEL is 3%. From firmware version 3.5, the DALI-PD has an additional operating mode. It can switch from operating mode DT4 (phase dimming) to DT7 (switch). In this mode, the DALI-PD behaves like a switch. The behavior in this mode complies with the DALI standard for DT7 devices (IEC 62386-208). In this mode, the switching characteristic is determined by comparing the virtual lamp power level (VDAP) with 4 switching thresholds.
